You can play it here.
Basically, nothing special on a glance. A slightly-humorous, obviously-cynical choose-your-own-adventure story with each path having vastly different versions of the characters, right?
...
Wrong.
Nothing in the game is a contradiction. Each different path merely represents different aspects of you, Faith, God, S(a)tan, and all the intricacies thereof. It takes either a good memory, multiple playthroughs, or good notekeeping to accomplish, but if you read all of the text on all of the pages, you realize that each and every path fleshes out those different elements of the characters...and through that fleshing out of them, goes into the philosophy debate tied into that aspect of them.
More than that, while each ending seems to be stand-alone, when you look at them, you realize that most of them tie together quite well. In that once again, they're showing characters, reacting in certain ways, just with a slightly different outcome based off of a decision you made early or late. Any individual path may seem somewhat-flat. May seem stereotypical, a bit rushed, perhaps slightly empty. But when you bring in aspects of the other endings into that ending, it gains a whole new meaning, beyond what it ever could have originally meant. Each answer, each end, gives the story new life that it otherwise lacks, no matter what the end result may look like individually.
By fleshing out the characters' different aspects, by having those endings end up crossing over into one another in generally-quite-subtle ways, the visual novel manages to bring out things that you could never get from linear storytelling. Among them, you basically have in its different endings an ever-looping philosophical debate. Each ending seems to have an Aesop attached to it, no matter how flat, mundane, or meaningful it may be. But the game is brilliantly in-depth again when you tie those philosophies with the other paths, and you realize that it's basically just different people on the podium arguing their different take on life. They have the same facts, but different interpretations of it, which you get to see by your choices. It explores the opinions many hold that God is crazy, evil, lazy, and/or apathetic, while also exploring the argument that God is bad, while also exploring the argument that God is not 'good' nor 'evil' in human terms because his philosophy works in mysterious ways humans can't hope to comprehend...
...And also explores all these things' counter-arguments, exploring how God is a voice of reason where humanity has none, that God is good, that God loves life, and has investment in it, exploring that God has a place in the world, and also the counter-argument about God working in mysterious ways in that His mysterious ways seem fairly...

Those arguments about God also apply to humanity, even stronger. The story does have a slight overall lean towards the cynical. So for humanity, the overall philosophy isn't so much good or evil, as much as it is not-strongly-evil vs. blatantly evil, in that humanity is portrayed as, like with a lot of forms of life, consuming resources from their surroundings in order to propagate their existence. The whole argument on humanity draws from basically every ending you see. The above one, for instance, is basically something that people taking a philosophy of humanity just being little more than animals might take, in that we still are doing the same things we were biologically programmed to do. Yet there's many more.
You have to be paying attention to these things quite closely in order to make some of these connections. But if you can connect the dots like I did, then the game's exploration of humanity, god, good/evil, and so much more with all those arguments and counter-arguments built in makes it an amazingly brilliant game to play. One that also has a very large amount of humor built in, and (though dry) quite excellent exposition.
Highly recommend a playthrough or two.
